Available in PDF, EPUB and Kindle. Book excerpt: Existing short and medium span bridges in seismic areas may be retrofitted using base-isolation bearing pads. The selection of pad stiffness characteristics and the decision on the location of the bearings are expected to have a significant effect on the magnitude and distribution of forces on bridge components during earthquakes. The objective of the study reported in this paper, is to investigate the effect of the various design parameters of the isolation system on the bridge response and the design forces on the piers and abutments. These design parameters include the pier stiffness, the elastic and post-elastic stiffness and the location of the bearing pads. A non-linear dynamic model of the bridge is developed to represent the behaviour of the base-isolated bridge system. In the development of model, the bridge deck is assumed to be rigid in its own plane. The model uses a time-dependent tangent stiffness matrix that is updated at the end of each time step. The data for ground motion is taken from actual strong motion earthquake records, and the ground motion is assumed to act in either the longitudinal or transverse directions of the bridge. The system is solved using the Newmark-Beta step by step numerical integration approach. It is concluded that the seismic response of the bridge is sensitive to small variations in the stiffness of flexible piers. The design forces can be shifted from the pier to the abutments by the proper selection of the location of the isolation bearing pads. The response and design forces of the bridge are found to be very sensitive to the stiffness characteristics of the bearing. Overestimation of the bearing stiffness can lead to serious underestimation of the design forces on the structural components of the bridge.

Available in PDF, EPUB and Kindle. Book excerpt: Because of their structural simplicity, bridges tend to beparticularly vulnerable to damage and even collapse when subjectedto earthquakes or other forms of seismic activity. Recentearthquakes, such as the ones in Kobe, Japan, and Oakland,California, have led to a heightened awareness of seismic risk andhave revolutionized bridge design and retrofit philosophies. In Seismic Design and Retrofit of Bridges, three of the world's topauthorities on the subject have collaborated to produce the mostexhaustive reference on seismic bridge design currently available.Following a detailed examination of the seismic effects of actualearthquakes on local area bridges, the authors demonstrate designstrategies that will make these and similar structures optimallyresistant to the damaging effects of future seismicdisturbances. Relying heavily on worldwide research associated with recentquakes, Seismic Design and Retrofit of Bridges begins with anin-depth treatment of seismic design philosophy as it applies tobridges. The authors then describe the various geotechnicalconsiderations specific to bridge design, such as soil-structureinteraction and traveling wave effects. Subsequent chapters coverconceptual and actual design of various bridge superstructures, andmodeling and analysis of these structures. As the basis for their design strategies, the authors' focus is onthe widely accepted capacity design approach, in which particularlyvulnerable locations of potentially inelastic flexural deformationare identified and strengthened to accommodate a greater degree ofstress. The text illustrates how accurate application of thecapacity design philosophy to the design of new bridges results instructures that can be expected to survive most earthquakes withonly minor, repairable damage. Because the majority of today's bridges were built before thecapacity design approach was understood, the authors also devoteseveral chapters to the seismic assessment of existing bridges,with the aim of designing and implementing retrofit measures toprotect them against the damaging effects of future earthquakes.These retrofitting techniques, though not considered appropriate inthe design of new bridges, are given considerable emphasis, sincethey currently offer the best solution for the preservation ofthese vital and often historically valued thoroughfares. Practical and applications-oriented, Seismic Design and Retrofit ofBridges is enhanced with over 300 photos and line drawings toillustrate key concepts and detailed design procedures. As the onlytext currently available on the vital topic of seismic bridgedesign, it provides an indispensable reference for civil,structural, and geotechnical engineers, as well as students inrelated engineering courses. A state-of-the-art text on earthquake-proof design and retrofit ofbridges Seismic Design and Retrofit of Bridges fills the urgent need for acomprehensive and up-to-date text on seismic-ally resistant bridgedesign. The authors, all recognized leaders in the field,systematically cover all aspects of bridge design related toseismic resistance for both new and existing bridges. * A complete overview of current design philosophy for bridges,with related seismic and geotechnical considerations * Coverage of conceptual design constraints and their relationshipto current design alternatives * Modeling and analysis of bridge structures * An exhaustive look at common building materials and theirresponse to seismic activity * A hands-on approach to the capacity design process * Use of isolation and dissipation devices in bridge design * Important coverage of seismic assessment and retrofit design ofexisting bridges

This book was released on 2004 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the past decade, seismic isolation systems have gained rapid popularity in the earthquake resistant design of bridge structures. This popularity has come in response to the inadequacy of earlier seismic design and retrofit methodologies. The mechanical shortcomings and subsequent failure mechanisms associated with the early elastic seismic design philosophy are first presented, followed by a study of the applicability of seismic isolation systems in bridge structures. This investigation includes a discussion of the susceptibility of simple span bridges to seismic failure, an overview of the behavior of base isolated structures, a detailed description of isolation system components, an explanation of the mechanics of elastometric isolation bearings, and a presentation of the linear theory of seismic isolation. The qualitative investigation of seismic isolation systems is supplemented by a quantitative nonlinear time-history analysis that illustrates the response of a simple span bridge to seismic excitation. The analysis examines the effects of the varying stiffness of a lead-rubber elastometric bearing upon structural response when subjected to the 1940 El Centro earthquake. The results confirm the expected behavior of isolated structures and emphasize the need for site-specific studies in the design of effective seismic isolation systems for bridge structures.

Available in PDF, EPUB and Kindle. Book excerpt: Earthquake engineering is the ultimate challenge for structural engineers. Even if natural phenomena involve great uncertainties, structural engineers need to design buildings, bridges, and dams capable of resisting the destructive forces produced by them. These disasters have created a new awareness about the disaster preparedness and mitigation. Before a building, utility system, or transportation structure is built, engineers spend a great deal of time analyzing those structures to make sure they will perform reliably under seismic and other loads. The purpose of this book is to provide structural engineers with tools and information to improve current building and bridge design and construction practices and enhance their sustainability during and after seismic events. In this book, Khan explains the latest theory, design applications and Code Provisions. Earthquake-Resistant Structures features seismic design and retrofitting techniques for low and high raise buildings, single and multi-span bridges, dams and nuclear facilities. The author also compares and contrasts various seismic resistant techniques in USA, Russia, Japan, Turkey, India, China, New Zealand, and Pakistan. Written by a world renowned author and educator Seismic design and retrofitting techniques for all structures Tools improve current building and bridge designs Latest methods for building earthquake-resistant structures Combines physical and geophysical science with structural engineering

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Base isolation systems are commonly used in the design of new bridges, and in the retrofit of existing ones. However, in Canada, base isolators are relatively new. They act as bridge bearings and isolate or decouple the superstructure from the underlying substructure to reduce the force generated in the structure by ground-motions. Horizontal displacements of isolators due to thermal and seismic loads are addressed in the Canadian Highway Bridge Design Code (CHBDC) CSA-S6-06 and adequate clearance must be provided. However, the Canadian code does not offer any guidance on how to combine these displacements. The objective of this thesis is to present the calculation methods of these displacements and to suggest different ways to combine them. Two bridges are analyzed in this thesis under Montreal's and Vancouver's thermal and seismic provisions to define a proposed thermal and seismic displacement combination formula for the design of base isolators in bridges in....

This book was released on 2021-12-15 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seismic resilience of new and existing structures is a key priority for the protection of human lives and the reduction of economic losses in earthquake prone areas. The modern seismic codes have focused on the upgrade of the structural performance of the new and existing structures. However, in many cases it is preferrable to mitigate the effects of the earthquakes by reducing the induced loads in the structures using seismic isolation and response control devices. The limited expertise in the selection and design of the appropriate system for new and existing structures is the main challenge for an extensive use of seismic isolation and response control systems in practice. This document aims to provide a practical guide by presenting a collection of the most commonly used seismic isolation and response control systems and a critical evaluation of the main characteristics of these systems. Comparisons of the key parameters of the design processes for new buildings with seismic isolation are presented, while the application of seismic isolation systems and response control systems for the retrofitting of existing structures is also examined, followed by various case studies from Greece, Japan, Mexico, New Zealand, and Turkey.
